High Resolution Vibrational–Rotational Spectrum of H2S in the Region of the ν2Fundamental Band

High-resolution Fourier transform spectrum of H2S in the region of 8500–8900cm−1

“…At the same time, the presence of strong local perturbations of the ''bright'' bands 3m 1 + m 2 and 2m 1 + m 2 + m 3 from the ''dark'' ones 3m 2 + 2m 3 and 2m 1 + 3m 2 allowed us to fit [4]. c Constrained to the value of corresponding parameter of the (0 1 0) vibrational state [7]. d Constrained to the values which correspond to the centers of the bands (1 1 2) and (0 1 3), 8877.73 and 8898.66 cm À1 , respectively, from [5].…”

The HITRAN 2004 molecular spectroscopic database

“…Line positions for 654 transitions in the (010)-(0 0 0) band were updated using experimental upper-state energy levels for H 2 32 S, H 2 33 S, and H 2 34 S isotopologues reported in Ulenikov et al [431] . while the lower-state energy levels were calculated using the rotational constants of Flaud et al [432] .…”

On the study of high-resolution rovibrational spectrum of H2S in the region of 7300–7900cm−1

“…Both the local mode properties, and the conditions of their destruction can be analyzed in the rovibrational spectra of H 2 S. As a consequence, numerous spectroscopic studies have been carried out on this molecule (see, for example, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]), beginning at the low frequency microwave region [1], up to visible transitions in the highly excited stretching bands ð70 AE ; 0Þ observed by the sensitive intra-cavity laser absorption spectroscopy, [18]. The ground vibrational state was analyzed in [1][2][3][4][5].…”

“…The ground vibrational state was analyzed in [1][2][3][4][5]. The lowest five poliads of interacting vibrational states, with v ¼ v 1 þ v 2 =2 þ v 3 , v ¼ 0:5, 1, 1.5, 2, 2.5, were discussed in [6][7][8][9][10][11], respectively. Highly excited stretching local mode states v ¼ 4, 4.5, 5, 6, 7 were considered in [12][13][14][15][16][17][18].…”
